[FL-3179] 1-Wire Overdrive Mode (#2522)

* Separate ibutton to its own module, add one_wire to f18
* Move onewire cli to a separate app
* Add definitions for normal and overdrive timings
* Update api definitions
* Add rough overdrive timings definition for onewire emulation
* Remove one_wire_host_timing.h
* Add rough overdrive timings for onewire host
* Improve overdrive mode
* Working overdrive mode from flipper to flipper
* Update thermometer example app
* Turn on otg power when running thermometer example app
* Implement reset overdrive switching
* Always exit out of overdrive mode
* Improve overdrive timings
* Fix typos
* Fix reset behaviour
* Use overdrive mode everywhere in DS1996
* Improve comments
* Bump API version
